Census and Statistical Maps of Cyberspaces

A "census" of Internet connectivity by countries has been undertaken at
regular intervals by Larry Landweber,
Computer Science Department, University of Wisconsin - Madison, USA.
The map opposite shows the differential levels of network connectivity
in September 1991.

The map on the left shows the connectivity position in
June 1997. The change in connectivity levels is clearly evident,
showing the spread of the Internet. Landweber's maps and data
tables are available.

A map showing
all the Internet interconnections for Hong Kong in December 1999. This
comprehensive census map of Internet infrastructure is a project of IDG Communications
in Hong Kong. The map is update quarterly.

Maps tracking the Internet infrastructure in South of
Korea produced by KR Network Information Centre (NIC). A whole series
of maps
over the past five years were produced using topological graphs
creating a useful census of the growing complexity the links between
ISPs and their capacity.

The top map shows the infrastructure in May 1995 and
the bottom one is from October 1999, clearly revealing the tremendous
growth in ISPs, connections and capacity.

Antonio Scarponi created an animated
map of the world showing the growth of Internet users from
1993 and predicted to 2015. The three images above are single frames
from the animation showing the state of the Internet world in 1996,
2001 and then projected for 2007.

The map uses a continuous cartogram
representation where the size of the country is based on the number of
Internet users rather than geographical area. Cartograms can be a very
effective means of visualizing demographic data as they highlight areas
based on where most people rather than simply territorial area.

Mike Jensen
is tracking the growth and development of the Internet in Africa,
including producing a range of statistical
maps and graphs. The two maps above show the changing level
of Internet access and international bandwidth between May 1996 and
December 1997.

Example frames
from an animated
map tracking the growth of the Internet in Europe through the
1990s. Several different map animations were produced by Eric Guichard,
at the Ecole Normale Superieure, Paris, using national level data from RIPE. Countries are
colour-coded according to hosts per capita and the green circles show
domains per capita. (Blue diamonds show the 1996 national population.)

These two maps of the USA show the geographical
deployment of high-speed, broadband Internet access technologies. The
map on the right looks at Los Angeles in greater detail.

The changing
geographic distribution of ISPs in the USA from September 1996 to
October 1998. Based on economic analysis of ISP markets by Shane
Greenstein and Tom Downes, Kellogg Graduate School of
Management, Northwestern University.

Diagrammatic
maps showing Thailand's
Internet Connectivity in September 1997 & 1998,
produced by Jumpot Phuritatkul and Thaweesak Koanantakool, NECTEC.

A census map of Internet
connectivity in Turkey, compiled by IIker Temir. It show the
state of connections at the end of June 2000. Check the website for the
most recent version.

A detailed mapping of the geography
of websites in France from February 2001. The map was created by
researcher Marina Duféal and uses proportional circles to
show the number of sites in each commune.

These maps provide a visual
census of network infrastructure. They are produced by the Technology
Policy Group as part of their NetmapUSA project
which benchmarks regional information infrastructure in the U.S.
